My purple fern leaf acacia is turning yellow and has a black tarry residue on the leaves throughout. I've hit it with a fungicide, but this doesn't seem to help much. I'm not sure if it's fungal or if it's a pest. I see tiny white bugs on the leaves, and when I prune and a branch falls on me, the bugs are all over me. I'm wondering if I should hit it with a neem oil as well as regular applications of fungicide. Any suggestions would be greatly appreciated.
